Special: Proving Innocence Episode 4: One call can change everything

In the fourth installment of the Proving Innocence series, the Notre Dame law students take on the case of Leon Tyson. He was convicted of a 2015 murder in Elkhart, but the Notre Dame Exoneration Justice Clinic believes he is innocent. He was sentenced to 63 years in prison. The case took a turn when the students and professor placed a call to the mother of a man who was also there during the crime. Her revelations intrigued the students, but the case may turn on the question of hair -- witnesses said the shooter had dreadlocks, but Tyson has long had alopecia, a condition that makes him bald. Tyson team leader Mackenna Krohn guides listeners through the twists and tangles of this case. *Edited description July 21, 2021.
